Shadow School Archimancy by White

From the acclaimed author of Nightbooks and The Thickety comes a spooky series, perfect for fans of Neil Gaiman, Adam Gidwitz, and Stranger Things!

Cordelia Liu knew Shadow School was going to be different. Black gates and ivied walls. Long hallways lined with old paintings. A tower with a window that looks like an eye. Different she expected; different she could handle. Still, Cordelia can’t shake the feeling that something’s not right—and that she’s being carefully watched.

The answer isn’t just in front of her eyes—it’s in her gym, next to the bulletin board, even in the cafeteria. The school grounds are filled with ghosts. Cordelia soon realizes she’s not the only one who can see them; her new friend Benji can too. Together with super-smart Agnes, the trio are determined to find out why the ghosts are there, and whether there’s a way to set them free. But the school was created with more sinister intentions, and someone is willing to go to extreme lengths to ensure that the ghosts remain trapped forever.
